Several weeks ago, I had one of my graphic artists work on the SAAB Griffen to use in a large format application. Once the file was finished, I gave it to a friend who output the file on his 84" plotter, using some new product samples as a test. Then yesterday, I affixed the art to the sound deadening material on the hood of my 9000. Thought I would share the pics. The material is not sticking the way I was hoping, so it most likely will be removed. Then I will plot out a paint mask and see how that works out.
The vinyl is not sticking to the material. So I am about to pull it off. Basically, I am going to do as you suggested, but I will be using Cirrus White, that is the color of the car and the overall color theme is White / Black.
I only have one concern about the spray process and that pertains to the crispness of the image edges, and there are a lot of edges ! I think there is going to be a significant feathering of the edges, that is why I tried the vinyl first.
